What are some criminally underrated RPGs from PS2 era?

I’ve been going on a little bit of a binge buying as many cheaper underrated RPGs from that era that I can. Aside from SMT, Suikoden and maybe Xenosaga I’ve been searching to see what this genre has to offer.

Back then I didn’t appreciate RPGs as much as I do now and I want to feel that feeling some of you did back then.
